oil tank - air extraction

[BonzoRosso]

Good evening to all,

Starting from a reservoir of origin we are trying to understand the motivation for which to a steel tank were air extractors that take air internally and carry it on the completely opposite side as seen from the attached scheme. Could someone explain this to me?
the object is attached under a truck by mating but is supportive tilts depending on the slope.
Was it not easier to go on the same side?

I would also like to understand what a fungus button could take on a tank, as I have a level with electronic float and overcoming the maximum limit there is an electro valve that closes the shutter.

thanks to all

If the vents are according to the longitudinal axis, I think that they are functional to the changes in the disposition of the uphill liquid and in braking/accelerated.

from a tank it is normally not extracted air, but the vapours produced by the evaporation of the fuel, in order to avoid excessive concentrations and pressures can create risks of deflagration. probably the opposite discharge is intended to prevent the operator, in the supply phase, to breathe these toxic vapors.
the fungus button (if you mean like those mounted on the machine tool panels) is to allow immediate detachment of the power to electrical devices, type electrovalve, in case of imminent danger (e.g. fuel dispersion outside the tank).

thanks for the answers, regarding the two discharges yes are aligned on longitudinal axis.
the fact of the discharges for the operator, of having an output on the opposite side would be right but the reservoir is unique therefore the exhalations would be extracted from both sides theoretically in an equal way.
the fungus button, you are like that of machine tools, in case of emergency should be pressed but should not be accessible to everything because if I close the valve and the path to the secondary tank, I can no longer feed the motorcycle/generator that should also work in phase of reloading fuel.
